I think it would make so much lives a lot easier if grep could support whitespace trimming of results.
Common example is when you grep-ing any tab/space indented code. This is when grep presents you with this:
klient2/box_zpros_zam_new.php:47: $('#fancy_zpros_zam_sel').attr('href', 'box_zpros_zam.php?id_clovek=' + id_clovek + '&id=' + ui.item.value);

when it would be so much better if it trims the starting (and ending) tabs/spaces and gave you this instead:
klient2/box_zpros_zam_new.php:47: $('#fancy_zpros_zam_sel').attr('href', 'box_zpros_zam.php?id_clovek=' + id_clovek + '&id=' + ui.item.value);
